Appl. No.:

7/277484

Inventors:

John W. Macpherson - Gig Harbor WA
Lee M. Acree - Tacoma WA

Assignee:

The Lucks Company - Seattle WA

International Classification:

A21D 200
A23L 110

US Classification:

426302

Abstract:

A method of using a silk screen to form thin, flat, flexible, free standing base shapes or transfers directly on release paper in their final form from fluid base shape material, all in one step. After drying, pictorial images are then silk screened onto the base shapes to produce the final edible image for decorating foodstuffs. Recipies for preparing the fluid base shape material and a novel machine for peeling the base shapes from the release paper with a spring steel blade are also disclosed.

International Classification:

US Classification:

210790

Abstract:

Apparatus, methods and media for filtering liquids are especially suited for insertion into an existing storm water catch basin. The filtration that occurs reduces concentration of storn water runoff pollutants including heavy metals, suspended solids, particles and oil and grease. While being able to handle the high flow rates of storm water runoff, the filters also remove small particles and oil and grease the filters are arranged such that overflow from uppermost filters, as they become clogged, is directed by overflow weirs to change direction to allow filtration by lower filters. Storm water surges during peak intensity are permitted to over flow directly into a catch basin to prevent ponding. The invention can also be used above ground to treat pumped liquid from industrial and environmental sources.
